Etymology

From New Latin concentrātiō (“(1550) action or an act of coming together at a single place; (1659) extraction or separation of one or more of the metals present in an alloy”). Compare French concentration, Spanish concentración, Italian concentrazione (last quarter of 16th century). Equivalent to concentrate + -ion. By surface analysis, con- + centre + -ate + -ion.
